IMPROVEMENT IN WATER-WHEELS.

flit: 5x1 211111: ninth in in flgcsz Enters new in making nut m the same.

TO ALL, WHOM IT. MAY CONCERNi Be it known that I, J. M. COOK, of Lake Village, in the county of Belknap, and State of New Hampshire, have invented anImpreved Water-Wheel; and I do hereby declare that the following is afnll and ex act description thereof, reference being had to the accompanying drawings making part of this specification- Figure 1 being a top view of the upper case or rim-of the wheel, showing also the operative portions "in view thereon. v p

Figure 2, a horizontal section through the wheel, ahd the gates and guides around it.

.Figure3, a central vertical section of the wheel proper.

Figure 4, abpttom view of the wheel.

Figure 5, a view of one of the buckets.

Like lettersdesignate corresponding parts in all of the figures.

My improvements are upon a turbine'wheel, to which the water is admitted through gates all around its periphery. l

The top plate or rim A of the case is connected with t'hobottom rim E (which supports the wheel-step D) by oblique water-guides H H, situated at uniform distances apart, and inclined inward, substantially as shown in fig, 2. l

Between the water-guides H Hare located the water-gates II, by whichthe water is list into the wheel, or shut as, or regulated in the quantity of flow. I

These gates are peculiarly arranged. They are pivoted'at z'z', near their centres, sofas to he nearly or exactly balanced around them on the two edges by the pressure of the water upon them, thereby enabling them to be turned or adjusted with great ease, however great the pressure of water against them. But this pivoting of the gates in the middle, between the stationary water-guides H Hgaccomplishesanother result of importance and salue,-nt|.uiely, that ofi furnishing two openings for the water to each gate, whereby the number of gates and of water-guides is reduced one-half, and the whole construction is simplified and cheapened.

The shape of the gates is such as to give proper admission and direction to the water, at the edges thereof, substantially as represented. v

The number of gatesand of guides may vary from size (as shown) to twelve, .or more, according to the size of the whecl.- 1

The gate-pivots z'z' extend up through' the upper rini or plate A, and have respectively attached to them cogsegment levers ff, which all gear into a central cog-wheel, F, substantially as shown in fig. 1. Thiscogwheel is moved by means of o. shaft, 9, and pinion 'or co'g-segment, G, whereby all the gates are operated equally and simultaneously.

The buckets L L of the wheel 13 are cast separately from the rim or plate, and have eaclin flanch, p, at the upper edge, by which they are secured to the rim or plate with bolts. Thus the buckets can he placed at any varying distance apart, and any convenient number on each wheel, say'i'rom twelre to thirty, according to the size of wheel. They are. also therehyrendily replaced if any one is broken or damaged.

This flnnchp is made thin at the outer edge, and graduallythickened to the inner edge, orwhere they join with the side of the bucket. This thickening gives an inclination inward and downward on the under side, so that the waiter strikes in a way to lift somewhat upon the buckets, and is itself directed downward thereby. Each bucket has its innerdischarge-edge, Z, curved-somewhat inward, and its lower discharge-edge m in like manner curved downward, while the twosaid edges, one nearly vertical and the other nearly horizontal, areconnected by a quarter-round rope, similarly curved outward and downward. This form gives an inward,'side, and downward bottomdischurge, bothdischarges bcingconnected in one sheet of water.

The discharge-end of,'each bucket receives a portion of the front part of each succeeding bucket, so that ,they are very compactly placed, and the size of the discharge-outlet is regulated by the relative situationbf the buckets.

This combined eonstruction produces anexcellent discharge and a. high percentage of power.

What I claim as my in ve'ntion, and desire to secure by Iifetters Patent, is-

'The water-wheel B, havingihdependent buckets LL, seem-ed to the upper plate by. inclined fianches p p, and formed with inwardly-curved discharge-edges Z Z, downwerdly'curved discharge-edges m m, and cutveui connecting-edges, substantially as an d for the purpose herein specified.

The above specification of my improved water-wheel signed by me, this 19th day of November, 1867.

J, M. COOK.
